In a particular embodiment, the CFT switch 130can also be coupled to a video-on-demand (VOD) server 136.

The application tier 104 can communicate with both the private network110 and the public network 112. In this embodiment, the application tier104 can include a first application tier (APP) switch 138 and a secondAPP switch 140. In a particular embodiment, the first APP switch 138 canbe coupled to the second APP switch 140. The first APP switch 138 can becoupled to an application server 142 and to an OSS/BSS gateway 144. Theapplication server 142 provides applications to the set-top box devices116 and 124 via the private access network 166, so the set-top boxdevices 116 and 124 can provide functions such as display, messaging,processing of IPTV data and VOD material. In a particular embodiment,the OSS/BSS gateway 144 includes operation systems and support (OSS)data, as well as billing systems and support (BSS) data.

In thisembodiment, the client gateway 150 can be coupled directly to the CFTswitch 130. The client gateway 150 can provide user access to theprivate network 110 and the tiers coupled thereto.

In a particular embodiment, the set-top box devices 116 and 124 canaccess the system via the private access network 166 using informationreceived from the client gateway 150. The private access network 166provides security for the private network 110. User devices can accessthe client gateway 150 via the private access network 166, and theclient gateway 150 can allow such devices to access the private network110 once the devices are authenticated or verified. Similarly, theclient gateway 150 can prevent unauthorized devices, such as hackercomputers or stolen set-top box devices from accessing the privatenetwork 110, by denying access to these devices beyond the privateaccess network 166.

For example, when the set-top box device 116 accesses the system 100 viathe private access network 166, the client gateway 150 can verifysubscriber information by communicating with the subscriber and systemstore 148 via the private network 110, the first APP switch 138 and thesecond APP switch 140. Further, the client gateway 150 can verifybilling information and status by communicating with the OSS/BSS gateway144 via the private network 110 and the first APP switch 138. TheOSS/BSS gateway 144 can transmit a query across the first APP switch138, to the second APP switch 140, and the second APP switch 140 cancommunicate the query across the public network 112 to the OSS/BSSserver 164. After the client gateway 150 confirms subscriber and/orbilling information, the client gateway 150 can allow the set-top boxdevice 116 access to IPTV content and VOD content. If the client gateway150 cannot verify subscriber information for the set-top box device 116,such as because it is connected to a different twisted pair, the clientgateway 150 can deny transmissions to and from the set-top box device116 beyond the private access network 166.

The acquisition tier 106 includes an acquisition tier (AQT) switch 152that communicates with the private network 110.

In a particular embodiment, the AQT switch 152 canbe coupled to a live acquisition server 154 that receives televisioncontent, for example, from a broadcast service 156. Further, the AQTswitch can be coupled to a video-on-demand importer server 158 thatstores television content received at the acquisition tier 106 andcommunicate the stored content to the client-facing tier 102 via theprivate network 110.

The operations and management tier 108 can include an operations andmanagement tier (OMT) switch 160 that conducts communication between theoperations and management tier 108 and the public network 112. In theillustrated embodiment, the OMT switch 160 is coupled to a TV2 server162. Additionally, the OMT switch 160 can be coupled to an OSS/BSSserver 164 and to a simple network management protocol (SNMP) monitor166 that monitors network devices. In a particular embodiment, the OMTswitch 160 can communicate with the AQT switch 152 via the publicnetwork 112.

In a particular embodiment during operation of the IPTV system, the liveacquisition server 154 can acquire television content from the broadcastservice 156. The live acquisition server 154 in turn can transmit thetelevision content to the AQT switch 152 and the AQT switch can transmitthe television content to the CFT switch 130 via the private network110. Further, the television content can be encoded at the D-servers132, and the CFT switch 130 can communicate the television content tothe modems 114 and 122 via the private access network 166. The set-topbox devices 116 and 124 can receive the television content from themodems 114 and 122, decode the television content, and transmit thecontent to the display devices 118 and 126 according to commands fromthe remote control devices 120 and 128.

Additionally, at the acquisition tier 106, the video-on-demand (VOD)importer server 158 can receive content from one or more VOD sourcesoutside the IPTV system 100, such as movie studios and programmers ofnon-live content. The VOD importer server 158 can transmit the VODcontent to the AQT switch 152, and the AQT switch 152 in turn cancommunicate the material to the CFT switch 130 via the private network110. The VOD content can be stored at one or more servers, such as theVOD server 136.

When a user issues a request for VOD content to the set-top box device116 or 124, the request can be transmitted over the private accessnetwork 166 to the VOD server 136 via the CFT switch 130. Upon receivingsuch a request, the VOD server 136 can retrieve requested VOD contentand transmit the content to the set-top box device 116 or 124 across theprivate access network 166 via the CFT switch 130. In an illustrativeembodiment, the live acquisition server 154 can transmit the televisioncontent to the AQT switch 152, and the AQT switch 152 in turn cantransmit the television content to the OMT switch 160 via the publicnetwork 112. In this embodiment, the OMT switch 160 can transmit thetelevision content to the TV2 server 162 for display to users accessingthe user interface at the TV2 server. For example, a user can access theTV2 server 162 using a personal computer 168 coupled to the publicnetwork 112.

The domain controller 146 communicates with the public network 112 viathe second APP switch 140. Additionally, the domain controller 146 cancommunicate via the public network 112 with the personal computer 168.For example, the domain controller 146 can display a web portal via thepublic network 112 and allow users to access the web portal using the PC168.

Proceeding to decision step 612, the set top box can determine whetherany of the series of self-tests has failed to complete. If none of thetests fail, the method can move to block 614 and the full test resultscan be transmitted to the repair center, or some other remote location.The test results can be transmitted to the repair center through anin-band interface or an out of band interface. For example, if videoservice channel has network connection issues, the set top box canupload, or report, performance data through secondary wireless channels,e.g., WiMAX, WiFi, etc. At block 616, the set top box can display thetest results at a display device coupled to the set top box. A customerservice representative, or technician, can use the test results in anattempt to fix, or repair, the problem.

Moving to block 618, the set top box can perform a root cause analysisin order to isolate the problem. At decision step 620, the set top boxcan determine whether the problem is isolated. If so, the method canproceed to block 622 and the set top box can indicate to the user and tothe repair center that the problem has been isolated. The method canthen end at state 624.

Returning to decision step 620, if the problem is not isolated, themethod can move to block 626 and the set top box can indicate to theuser and the repair center that further analysis is required. The methodcan then end at state 624.

Returning now to decision step 612, if any test fails to complete, themethod can move to block 628 and the set top box can transmit a failedtest message to the repair center. Thereafter, at decision step 630, itcan be determined whether to retry the failed test. This determinationcan be based on a request from the repair center, i.e., the repaircenter can request that the set top box repeat the failed test. If theset top box determines to repeat the failed test, the method can returnto blocks 602 through 610 and repeat the failed test, or tests.Conversely, if the set top box determines not to repeat the failed test,the method can move to block 632 and the set top box can transmit thepartial test results to the repair center. Thereafter, the set top boxcan indicate to the user that further testing is required. The methodcan then at state 624.
